nrg_alpha Posted February 26, 2009 Share Posted February 26, 2009 Ok, so I am over at macrumors.som and noticed this article. The claim on this page sites: CNet benchmarked Safari 4's Javascript and found it to be 42x faster than IE 7, 6x faster than IE 8 and the fastest compared to any browser The article states that it's using sunspider for their tests (from what I gather, this includes stuff like 3d, raytracing and the like.. I tried running the tests on that page, it was taking a while, so I aborted). My understanding is that there are different benchmarking tools out there for Javascript that target different javascript aspects (rendering, DOM navitagion / manipulation, etc...) When I began playing with the sample javascript demo, I personally found that on my chitty laptop, Chrome (1.0.154.48) chewed up Firefox 3(3.0.6) as well as Safari 4 Beta (win) (we won't even bother going into the details of how IE 7 performed.. because it didn't... at all.. just hung there). Therefore, at least from these demos (from a frame rate standpoint), from what I am experiencing, Chrome's javascript engine seems to be much faster than Safari 4's (haven't tested this on Minefield / Opera 10 Alpha yet). Granted, none of this is scientific per say.. but rather 'demonstrative' and Chrome demonstrated quite handedly.

rhodesa Posted February 26, 2009 Share Posted February 26, 2009 I'm guessing they used Safari 4 on a Mac, which most likely runs faster then the Windows version Link to comment https://forums.phpfreaks.com/topic/146954-javascript-speed-differences/#findComment-771618 Share on other sites More sharing options...
nrg_alpha Posted February 26, 2009 Author Share Posted February 26, 2009 Hmm.. would the javascript engine actually be that much faster on a Mac? If so, it's quite indicative of how bad window's Safari version is in this regard...

Mchl Posted February 26, 2009 Share Posted February 26, 2009 As far as I remember it wasn't all that faster from FF3, when I tested my ExtJS based application. (Actually, I saw no real difference at all) Link to comment https://forums.phpfreaks.com/topic/146954-javascript-speed-differences/#findComment-771710 Share on other sites More sharing options...
